It’s a good book, but voluminous. I did buy it thinking that I could solve it. But even after studying for 14 hours per day I didn’t have enough time to solve it.
Dinesh includes question from old exams and state exams, back from 1990’s. The question is set at a different level and this lowers our confidence.
My advice, solve your NCERT, the module you get from your institute (if you have joined any) and if you’re still not satisfied, try solving NEET guide for physics (MTG) OR Chemistry on fingertips (MTG).
Once a teacher of mine said
Don’t read thousands of book once, it won’t help you as much as reading a single book thousand times will help you.
Hope it helps and best of luck.
